The electrons are placed into atomic orbitals that determine the atom's various chemical properties. The number of neutrons in a nucleus usually has very little effect on an element's chemical properties (except in the case of hydrogen and deuterium).
According to proponents of the metabolic typing diet, the three metabolic types should eat the following foods: Protein types: Diets that are rich in protein, fats and oils, and high-purine proteins such as organ meats, pate, beef liver, chicken liver, and beef.
